'IGNITION-TIMER.

Specification of Letters Patent.

Patented Apr. 26'; 1910.

To all whom it may concern:

Bc il known that l', linnn-xs l. Baonn.

i mxo, a citizen of the United States, residing at Dayton," in the county of Montgomery and. State of Ohio, have invented certain new and useful linprovcn'icnts in Ignition- Tiinei's; and l do declare the following to be a full, clear, and exact description of the inif'cntion, such as will enable others skilled in the art to which it ap'pertains to makel and use the saine, reference being had to theaccompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relatos to improvements in igniter timing devices for internal conr bustion engines of the type adapted yfor motor vehicles. Itis well-known that the speed of such engines is regulated by advaucing and retarding the time of ignition,

by means of arocking switch. f Hcretofore, it has been the practice to connect such switch or timing device with the battery and coil by means of flexible connections, and.

owing tothe continuous/twisting of said' connections, more or4 less annoyance is caused due 'to the breaking of thesame.

The obJect of the presentlnventionls to obviat/e this difficulty by relieying the connections of any torsional strain'.

To this end, my invention comprises -a' stationary outer terminal support,k andan inner rocking Contact ring combined with an inner rotating'contact member, as hereinafter more fully described.

In the accompanying drawings, Figure 1, is a horizontal sectional viewf of my improved ignition timer on the line a a.' of Fig. 2. Fig. 2, is a verticalsectional view on the line b b of Fig. 1.

In the following specification, similar ref erencc characters indicate corresponding parts.

The outer cylindrical casing 1 is rigidly -fsecurable to the engine (not shown) by a clipV 22 and is therefore stationary. On thc j outer circumference of said casing is'mountled a plurality ofterminal binding posts 2 corresponding-in number to the cylinders of the engine, .and insulated l'from said casing by sleeves 3. On the inner ends of said binding osts 2, leaf spring brushes 5 are connecte which are also insulated from the casing 1 by a continuous strip of liber 4 which is laid against theinner circumfer-V ence of said casing. The free ends of the "brushes 5` engage the extensions 6 of thcr contact members 7 which are mounted on the inner rocking ring or head 8. .The contact members 7 are insulated from said head by a ring of fiber 9 and are attached to said head b each ot ier by a series ofsem'i-circular pieces of-iber 25. The .screws 12 also pass through a ring of fiber or insulating materiall on the top of said head and which insulates said screws from said contact members 7. The insulating members25 are attached to the ring or head 8 by means of screws 11, and the extensions are attached to said members 25 by screws 26. The rocking ring or head 8 so sup orting said contact members 7, is provide ,with a hub la which projects through the bottom of the `casing 1 and to which is attached a-lever 15 byineans of spark lever of the motorvehicle by link and the drawings as they are well-known featurcs of motor vehicles. Rotating within the hublt is a shaft`21 driven from. thetwo to one shaft (not shown) of theengine in a well-known manner. A i

TheA upper end of the shaft 21 carries a lever 18 pivoted thereto at 19 and carrying aroller'li' which rides on the inner surfaces members' 25. Whenever said roller 17 engages one of the contact members 7, the cir*- Acuit is closed, and the charge is ignited in the engine cylinder. Vhen it is desired to advance the spark, the Contact members 7 are rocked in a direction opposite `the direction of .rotation of the roller 17, and vice pressed outwardly to insure a constant engagement with the inner circumference o f the rocking head, by means of a spring 20 which is hooked to' an end of said lever and to a projection on the shaft 21. The outer stationary casing 1 is inclosed-at the top by a cap 23 upon which is mounted a binding post with nuts 24. between which is secured the terminal of a ground wire.

I do notdesire'to limit myself to the spe'- cific details shown and described` herein, as it will be apparent that modicationsmay .be made Without'departing from the fundamental objects and purposes of my invention which contemplates a stationary mounting of the terminals of the 'conductors by means. of a stationary outer terminal supjscrews 12', and are insulated from of the contact members 7 and insulating versa The roller-supporting lever 18 is a clamp, 16. The lever 15 is connected to the lever connections which 4are not shown in y port combined with an inner rocking contact head or ringwith a rotating contact member.

Having described my invention, claim:

l. In an ignition timing device, the comn bination with an outer casing having an electrical terminal mounted thereon, ofen inner rocking head having a Contact mounted thereon, a leaf spring brush forming an electrical connection between the terminal on said casing and the contact member on the rocking head, and a rotating shaft having a Contact member thereon `adapted to engage said rocking head contact during the rotation of said shaft.

2. In an ignition timingdevice, the coinbination with a stationary outer casing havweeen.

ing u, plurality of terminale mounted thereon, of an inner rocking .head or ring having :t plurality of lContact members thereon, brushes consisting` of leaf springs forming electrical connections between said terminals and seid contact members, nfl :i rotating shaft having a Contact member thereon adapted to malte electrical Connections with said rocking head contacts during the revo` lution of said shaft.

In testimony whereof I alix my signature, 1n presence of two Witnesses.
